[0034] like Figure 1-12 As shown in the figure, the outdoor distribution cabinet is described in detail:

[0035] An outdoor power distribution cabinet includes a cabinet body 101, a vertical slot 102 is recessed outward at the rear end of the cabinet body 101, a lifting frame 302 is provided in the vertical slot 102 for lifting and sliding, a vertical screw 301 is threadedly connected through the center of the lifting frame 302, two fan seats 303 are connected inside the lifting frame 302, and fans 304 are fixed at the front ends of the two fan seats 303.

[0036] When in use, the cabinet 101 is placed vertically on the ground, and the two fans 304 are started to blow air forward, thereby forming a blowing and cooling for the electrical components in the cabinet 101. At the same time, the first motor installed at the upper end of the vertical slot 102 is started, and the output shaft of the first motor drives the vertical screw 301, so that the vertical screw 301 rotates back and forth intermittently. Then, through the threaded connection between the vertical screw 301 and the lifting frame 302, the lifting frame 302 can be lifted and lowered in the vertical slot 102, and then the two fans 304 are driven to lift and lower back and forth through the two fan seats 303, thereby forming a comprehensive coverage of the electrical components inside the cabinet 101, which is blowing and cooling, thereby improving the heat dissipation effect.

[0037] A fixing sleeve is provided at a position on the bottom plate of the cabinet 101 corresponding to the vertical screw 301 for installing the limiting vertical screw 301 so that the vertical screw 301 can only rotate about its own axis.

[0038] Further:

[0039] A cross-connecting plate 305 is rotated at the ends of the two fan seats 303 away from the fan 304, and a long hole 306 is provided in the middle of the cross-connecting plate 305. A power shaft rotates on the lifting frame 302, and an eccentric shaft 307 is fixed at the eccentric part of the lower end of the power shaft, and the eccentric shaft 307 slides in the long hole 306.

[0040] The fan seat 303 is composed of a seat body and a vertical axis. The vertical axis passes through the seat body and is rotatably connected to the lifting frame 302 to form an installation of the fan seat 303 and the lifting frame 302. The rear end of the seat body is a duckbill structure. The two ends of the cross-connecting plate 305 are respectively located in the duckbill structures at the rear end of the two seat bodies and are rotatably connected by a penetrating pin shaft. The spacing between the two pin shafts penetrating the duckbill structures and the cross-connecting plate 305 is the same as the spacing between the two vertical axes, thereby forming a parallelogram structure. When the second motor installed on the lifting frame 302 is started, the output shaft of the second motor rotates on the lifting frame 30 2 is transmitted, thereby driving the eccentric shaft 307 to rotate eccentrically with the power shaft as the axis, thereby forming the sliding of the eccentric shaft 307 in the long hole 306, and then forming the swing of the cross-connecting plate 305 in the left and right directions, which will simultaneously drive the two fan seats 303 to swing left and right with the corresponding vertical axis as the axis, thereby causing the two fans 304 to swing left and right with the corresponding vertical axis as the axis, further expanding the blowing range of the two fans 304, and further achieving the purpose of comprehensive coverage of the electrical components inside the cabinet 101 to blow through the heat and improve the heat dissipation effect.

[0041] Based on the above embodiment:

[0042] A bottom box 104 is provided at the lower end of the cabinet 101, and a water pump 401 is provided in the bottom box 104. The water pump 401 is used to supply water to a water pipe rack 402 provided inside the cabinet 101. The water pipe rack 402 is located between the fan 304 and the electrical component mounting frame. Return pipes 403 are symmetrically provided at both ends of the upper end of the water pipe rack 402 to guide the water in the water pipe rack 402 back to the bottom box 104.

[0043] The bottom box 104 is used to hold cooling water and is buried below the ground during installation. The bottom box 104 surface is isolated from the ground environment, that is, the ambient temperature of the cabinet 101. The low temperature environment deep in the ground ensures that the cooling water in the bottom box 104 is in a low temperature state. The water pipe rack 402 is composed of a lower transverse pipe, an upper transverse pipe and a plurality of vertical pipes. The plurality of vertical pipes are evenly connected and arranged side by side between the lower transverse pipe and the upper transverse pipe. A connecting pipe connected to the water pump 401 extends from the middle of the lower transverse pipe. The connecting pipe runs through The bottom plate at the lower end of the cabinet 101 and the two ends of the upper horizontal pipe are respectively connected to the two return pipes 403. When in use, the water pump 401 is started, and the water pump 401 pumps the cooling water in the bottom box 104 to the lower horizontal pipe, and then enters the upper horizontal pipe through multiple vertical pipes, and finally returns to the bottom box 104 through the two return pipes 403, forming a circulation flow of cooling water in the cabinet 101, thereby cooling the air inside the cabinet 101 through the water pipe rack 402, further improving the heat dissipation effect of the electrical components in the cabinet;

[0044] The heat absorbed by the cooling water will enter the bottom box 104, and finally transfer the heat to the ground at the bottom of the bottom box 104 to ensure the cooling water is at a low temperature.

[0045] At the same time, by arranging the water pipe rack 402 between the fan 304 and the electrical component mounting frame, the air blown by the fan 304 will first come into contact with the water pipe rack 402, and then pass through the gaps in the water pipe rack 402 to be blown to the electrical components. This is equivalent to cooling the air blown by the fan 304 through the water pipe rack 402, and dissipating the heat when it is blown to the electrical components, further improving the heat dissipation effect of the electrical components.

[0046] Further:

[0047] A wiring tube 108 is provided through the center of the bottom box 104 for allowing wires and cables to enter the cabinet 101 from the lower end, thereby ensuring that the cabinet 101 has good sealing performance. Since the lower end of the wiring tube 108 is directly connected to the ground, moisture may enter the cabinet 101. Therefore, after the installation of the wires and cables is completed, the wiring tube 108 can be sealed with a colloid.

[0048] Further:

[0049] An extension lumen 105 extends downward from the lower end of the bottom box 104 .

[0050] By setting the extension lumen 105, the extension lumen 105 is further extended underground, so that the cooling water in the bottom box 104 can further contact the underground low-temperature environment through the extension lumen 105, further ensuring the low temperature state of the cooling water in the bottom box 104. Moreover, the extension structure is only the pipe body. During installation, it is only necessary to drill a hole corresponding to the pipe body at the corresponding position on the ground, which reduces the amount of engineering work during installation.

[0051] Meanwhile, the number of the extension lumens 105 can be multiple.

[0052] Further:

[0053] A spiral frame 107 is provided in the extension tube cavity 105 , and the upper end of the spiral frame 107 is rotatably connected to the bottom plate of the cabinet 101 .

[0054] In order to ensure that the temperature of the cooling water in the extension tube cavity 105 is relatively balanced with that in the bottom box 104, a third motor is installed on the bottom plate of the cabinet 101 to drive the spiral frame 107, so that the spiral frame 107 rotates in the extension tube cavity 105. The rotating extension tube cavity 105 will spirally drive the water in the extension tube cavity 105 to flow upward, thereby forming a mixture of the cooling water in the extension tube cavity 105 and the cooling water in the bottom box 104, ensuring that the water temperature in the two is balanced; thereby forming a low temperature state of the overall water temperature, ensuring the heat dissipation effect;

[0055] At the same time, there is a gap between the spiral frame 107 and the inner wall of the extension tube cavity 105, which facilitates the cooling water in the bottom box 104 to flow into the extension tube cavity 105 through the gap, further improving the mixing efficiency.

[0056] Further:

[0057] The electrical component mounting frame includes fixing plates 103 symmetrically fixed to the left and right sides of the cabinet 101 . Both fixing plates 103 are provided with a plurality of mounting holes, and a plurality of crossbeams are installed between the two fixing plates 103 .

[0058] The crossbeam frame includes a crossbeam plate 201 for mounting electrical components. Magnetic plates 202 are fixed to both ends of the crossbeam plate 201 , and plug posts 203 are fixed to both magnetic plates 202 .

[0059] The crossbeam plate 201 is used to install electrical components. When the crossbeam plate 201 is installed on the two fixed plates 103, the two magnetic plates 202 are respectively corresponding to the two fixed plates 103. The magnetic force between the magnetic plate 202 and the fixed plates 103 will automatically make the magnetic plate 202 close to the fixed plates 103. When the plug 203 is inserted into the corresponding mounting hole, the magnetic plate 202 is magnetically attached to the fixed plates 103, forming a quick limit installation of the crossbeam plate 201 and the two fixed plates 103; it also facilitates quick disassembly, and you can directly pull the crossbeam plate 201 away from the fixed plates 103. In actual use, the number of crossbeam plates 201 can be installed as needed.

[0060] Further:

[0061] Two pin shaft seats 106 are fixed on both sides of the left and right sides of the front opening of the cabinet body 101. A pin shaft 502 rotates in each pin shaft seat 106, and a door panel 501 is fixed between the two pin shafts 502 on the same side.

[0062] The pin seat 106 is located on the left and right side surfaces of the cabinet body 101, and the door panel 501 is L-shaped, that is, a right-angled bent edge is provided at the end of the pin 502, so that when the front opening of the cabinet body 101 is closed, the main panel of the door panel 501 is attached to the front face of the cabinet body 101, thereby ensuring the overall sealing of the cabinet body 101, and the two door panels 501 are symmetrical.

[0063] Further:

[0064] A bracket 601 is slidably provided on the upper end plate of the cabinet 101 , and a spring 602 is provided between the bracket 601 and the upper end plate of the cabinet 101 .

[0065] The elastic force of the spring 602 will push the bracket 601 to slide downward, and then the upper end of the bracket 601 will press against the upper end plate of the cabinet 101. At this time, the bracket 601 will fit on the front end surfaces of the two door panels 501, thereby forming a limit for the two door panels 501 and ensuring that the two door panels 501 are in a closed state.

[0066] When the door panels 501 need to be opened, the bracket 601 is pushed upwards to make the bracket 601 move upwards against the elastic force of the spring 602 , and then the bracket 601 is separated from the two door panels 501 , and the door panels 501 can be opened.
